We all know what it’s like to have a bad night’s sleep or two. If the situation persists, it can be hazardous for your health. You can learn more about the impact here.

Sleep is essential for babies (and us). It’s when the brain goes to work to help them embed memories, what they learned that day, and sets us up for healthy growth.1 Conversely, poor sleep in infants has been linked to problems later in life.1

If a baby is keeping you awake that’s probably not good for either of you. Obviously, newborns don’t sleep for long in between feeds and nappy changes, and that’s to be expected. But if your child is struggling to sleep, perhaps you could use some help.

That’s where a sleep noise machine might come in handy.

What is a sleep noise machine?

Sleep noise machines usually play what’s called ‘white noise’. White noise refers to a noise that contains a wide range of audio frequencies. It’s best described as a static-like sound, a bit like a fan or air conditioner.

While it might seem a bit strange to use noise to help infants sleep, it actually provides a level of comfort. That’s because when the baby is still in the womb, they’re constantly exposed to the sounds of mum’s body. Heartbeat and shushing sounds as blood rushes around the body. In fact, it’s estimated that the noise in the uterus could be between 70 and 91 decibels. To put that in perspective, a vacuum cleaner is in the same range.4

White noise machines try to simulate the ‘background’ sounds of the uterus. Most importantly, the machines tend to mask more intermittent noises that could wake a child. Things like doorbells or car horns tooting, or siblings yelling somewhere nearby.

One study showed that 80% of newborns were able to fall asleep after five minutes of exposure to white noise.5

Some sleep machines come with the option of playing other sounds, like rain, or waves, often called ‘pink noise’.6 Others include the ability the play soothing lullabies. But if you really want the baby to feel right at home, choose a sound machine that can play a beating heart. For example, the Welcare Sleep-Tight Sleep Sound Machine allows you to record your own unique heartbeat and play it back to your baby for the ultimate comforting sound as well as 5 relaxing sounds and 4 lullabies.

Another feature to look out for in a sleep sound machine is the ability to control volume. While the benefits of white noise in helping infants sleep is well established, medical authorities warn that you need to choose carefully, some machines can exceed recommended noise limits. The Welcare Sleep-Tight Sleep Sound Machine features 7 audio levels to ensure it’s not too loud.

Once the baby’s asleep, you might want to try the machine yourself – it could help you sleep and enhance your work performance.3
